as described in this sample project from @soe78:
https://github.com/soe78/CxfDemo

the manually registered request mapping/hello doesn't show up in the boot dashboard properties view tab for the request mappings.

The live data from the actuator does contain information about this mapping:

{mappings=[/hello], name=httpServlet, className=demo.config.ServletConfig$1}

Even though the className can't point the tooling towards the exact location of the manual registration, the data allows the tooling to at least navigate to the referenced inner class (in this example case).
